PIPE AND THE LIKE FOR- SMOKING TOBACCO.

Application filed January 9, 1926, Serial No. 80,143, and in Great Britain December 9, 1925'.

This invention has reference to pipes and the like, for smoking tobacco, in which provision is made for preventing nicotine de-' posit passing to the mouth of the smoker and for obtaining a cool smoking effect, and relates to an improved device of the kind which consists of a tubular chamber arranged in i the stem and having at each end an inter,- nally projecting and outwardly extending tube which respectivel communicate with the bowl in the moutipiece, the said improved device being designed with the object of insuring greater reliability and efliciency than has generally been experienced with E5 the contrivance heretofore proposed for the purpose.

The improved device consists essentially of an elongated hollow body which forms the entrapping chamber and has at each end a tube which projects a short distance into the cavity or chamber of the body and extends a certain distance from the same, the one tube extending from the body into the bottom of the bowl and the other, also from the body, into the-mouthpiece at its junction with the stem. These tubes are secured in the ends of the body by push-in or screw fittings and the one which extends to the bowl is formed with transverse. or lateral perforations to facilitate draught and the entry of the smoke. The said body is of an exterior diametral measurement adapted to reside in the bore of the stem so as to fill or nearly fill the same; the said bore being i somewhat larger than usual when necessary.

The body is divided and jointed centrally or thereabouts of its length and the parts are united by push-in or screw connecting means.

The device thus presents a kind of rattrap for collecting the nicotine, the relative disposition of the tubular extensions ensuring the entrapping of the said deposit in the chamber so as to effectually prevent its passage into the mouthpiece. The smoke also becomes cooled on its passage through the chamber to the mouth of the smoker and further is deprived of a certain amount of moisture.

In order that the invention may be readily understood and carried into effect same will now be more fully described with reference to the accompanying drawings, in which Figure l is a side elevation of the device detached or removed from the pipe.

threaded for joining together and for the reception of screw threaded tube ends;

Figure 6 is a further modified form in which the body parts are formed with interiorly projecting flanges which provide sleeves for receiving the tube ends.

a indicates the elongated hollow body, I) the tube which extends at one end therefrom into the bottom of the bowl d and c the tube which extends at the other end and is attached to the mouthpiece c. This trapping device is conveniently formed by inserting or pushing the tubes 6 and 0 into end per-forations in the body as shown clearly in Figures 1 to 4 of the drawings. The said body may however be screw threaded as shown in Figure 5 for cooperation with correspondingly screw threaded tube ends. If desired, the body may be formed with interiorly projecting flanges adapted to provide sleeves for the reception, by push-in or screw joints, of the tube ends. Such a. construction is shown in F igurefi in which the interiorly projecting flanges are indicated at a".

The body a is divided centrally or thereabouts of its length so as to facilitate cleaning, the parts being arranged for connection by means vof a push-in or screw fitting as shown at a in Figures 2, 4 and 6 or at a in Figure 5.

The tube 6 which extends into the bottom of the bowl d, Figure 3, is provided with small perforations b with the object of in creasing or improving the draught or suction effect.

The tubes 6 and 0 may project equally dist-ant from the respective ends of the body a and the extent of interior projection is comparatively small and also equal or there- 105 abouts for each length of tube. Variations in such details may, however, be found desirable to suit different patterns or styles of pipes.

The device is preferably constructed of 119 metal, such as aluminium, but any other material suitable to the purpose may be employed in its construction.

The device herein described provides a cooling chamber for the smoke and ensures the trapping of all nicotine from the pipe bowl as well as any saliva from the mouthpiece.

I claim v 1. In a tobacco pipe having a bowl 't'ormed with a stem which has a mouthpiece fitted to extend therefrom, the provision, in the stem, of an elongated bipart hollow body, whereof the parts are connected about the mid-point of its length, and the ends are adapted to connect with tubular extensions which extend into the said body and re spectively enter the bowl and the mouth piece.

2. In a tobacco pipe having a bowl formed with a stern which has a mouthpiece fitted to extend therefrom, the provision, in the stem, of an elongated bipart hollow body .to extend therefrom, the provision in the stem, of an elongated bipart hollow body whereof the parts are connected about the mid-point of its length and the ends are adapted. to connect with tubular extensions of which one has its walls perforated and projects into the said body and enters the bottom of the bowl and the other has solid walls and projects into the said body and enters the mouthpiece at its junction with the stem.

In witness whereof I have hereunto subscribed my signature this 23rd day of December, 1925.

LOUIS AUGUSTUS DRAVERS.
